The report from the UN Intergovernmental Panel on Climate Change runs 2,610 pages in 32 volumes, the Associated Press informs us. Its chairman, Rajendra Pachuari, told the AP the report is “a call for action” and unless “greenhouse emissions” are reduced, the effects of warming “could get out of control.” The AP said the report is aimed at world political leaders.
One of the 70 authors, an official with the International Federation of the Red Cross and Red Crescent societies, said, “If we don’t reduce greenhouse gases soon, risks will get out of hand.” He said the latest report is broader than previous ones and includes risks and vulnerability. The word “risk” is used an average of 5½ times per page in the 49-page summary.
Another author, Richard Tol, economics professor at Sussex University in England, told Reuters he pulled out of the writing team because the drafts were “too alarmist.” He said, for example, farmers could raise new crops if the climate becomes hotter, wetter or drier. “They will adapt,” he said. “Farmers are not stupid.” The report plays down possible economic benefits of low warming levels, he said. “It is … obvious that there are positive impacts of climate change.”
A new report from the American Association for the Advancement of Science also gives dire warnings about global warming, asserting “about 97 percent of climate scientists have concluded that human-caused climate change is happening.” However, says the New York Times article citing the report, “That is not the same as claiming that all questions about climate change have been answered. In fact, enormous questions remain, and the science of global warming entails a robust, evolving discussion.”
And to cap off the latest round of alarms, climate change causes crime, according to an analysis by Matthew Ranson, an economist with consulting firm Abt Associates. His analysis, published in February by the Journal of Environmental Economics and Management, was based on a 30-year study of crime and weather in 2,997 U.S. counties.
“The results show that temperature has a strong positive effect on criminal behavior with little evidence of lagged impacts,” he wrote. “Between 2010 (sic) and 2099, climate change will cause an additional 22,000 murders, 180,000 cases of rape, 1.2 million aggravated assaults, 2.3 million simple assaults, 260,000 robberies, 1.3 million burglaries, 2.2 million cases of larceny and 580,000 cases of vehicle theft in the United States.”
Ranson said his work was supported by a Harvard University Dissertation completion fellowship and Abt Associates. He acknowledges his results indicate only a fairly small increase in crime, for example, 2.2 more murders and 3.1 percent more rapes over a period of nearly a century. “From a statistical standpoint,” he said, higher outdoor temperatures cause crime to increase.
The question is: What doesn’t global warming cause?
